User blog:L1842947/Female Protean Froakie with Toxic Spikes

I just hatched a female Protean Froakie with Toxic Spikes. I want to know if anybody has answers to the following questions: Is Protean Froakie any good? How much would anyone else want this? I'm going to keep it stashed away in my box for some time until I get answers to my above questions.
 * Is this information on how Hidden Abilities are passed on to offspring true for Brick Bronze?  In other words, if I breed this Froakie with a male from the same egg group, does the offspring have an 80% chance of having Protean?
 * Is this information about relearning egg moves true for Brick Bronze?  In other words, if this Froakie forgets Toxic Spikes, can I take it to the Move Reminder in the Battle Colosseum and teach it Toxic Spikes again?  I'm asking because I felt I tried this already with another Froakie I taught Toxic Spikes to and it couldn't relearn the move.  If I pull this Protean Froakie out of daycare after some time, Toxic Spikes will have been overwritten and I won't be able to teach it to any other Froakie.
